BEDPOST LOCK.

Application filed January 7, 1925. Serial No. 991.

To all whom it may concern:

Be it known that I, EDWIN C. MCFAR- LANE, a citizen of the UnitedStates, residing at N o. 355 East 51st Street, borough of Brooklyn,county of Kings, State of New York, (whose post-office address is 203Lafayette Street, borough of Manhattan, city of New York, State of NewYork), have invented a new and useful Bedpost Look, of which thefollowing is a full, clear, and exact description.

My invention relates to of the wedge type, and the object thereof is toprovide a lock of the type referred to, which is simple and rigid inconstruction and which can be manufactured economically.

I attain this object by the construction illustrated in the accompanyingdrawing in which- Figure 1 is a top plan view of a bedpost provided withan embodiment of my invention;

Figure 2 is a vertical section on a line 22, Figure 1;

Figure 3 is a perspective view of the wedge carrying plate;

Figure 4: is a perspective view of the bedpost bracket into which thewedge of the plate fits; and

Figure 5 is an elevation of the wedge carrying plate from the wedge sidethereof.

Referring to the drawing, 10 is a tubular bedpost to which a postbracket 11 is cona bedpost lock nected by means of rivets 12. Preferablythe side 13 of the bracket which contacts with the bedpost is curved inconformity with the post 10. The tube at the bracket is reinforced by aliner 14, so that the rivets 12 will connect the bracket 11 rigidly tothe bedpost 10. The side 15 of the bracket which extends from the posthas a tapering slot 16, open at the top, as best shown in l igin'es 1, 2and 4.

A wedge 17 fits into the slot 16. The wedge is partially sheered outfrom a plate 18 and bent or ressed to one side of that plate so thatwhen the wedge 17 engages the slot 16, the plate 18 contacts with theadjacent face of the side 15 of the bracket 11. The plate 18 has an arm19 extending laterally of the wedge, and the arm is offset toward thewedge so that the arm and the wedge are lying substantially in a commonplane. The wedge and the arm have apertures 20 and 21 respectively, sothat the wedge plate 18 could be secured by means of rivets 22 and 23 toangle iron 24 forming part of the bed frame.

As it will be seen, the wedge 17 and the arm 19 are off-set to theextent equivalent to the thickness of the side 15 of the bracket 11.Vhen thewedge plate 18 is secured to the angle iron 24, as shown inFigures 1 and 2, they both, that is, the angle iron and the plate 18,firmly embrace the side 15 of the bracket 11 when the wedge 17 isengaged into the slot of the bracket.

hen holes 20 are punched in the wedge 17, the sides of the wedge at theholes are slightly bulged, as best shown in Figure 5 and indicated asbosses 25. It is self-evidentthat the punching of the holes 20 to obtainthe bosses25 on the sides of the wedge must be done after the sheeringand bending of the wedge 17 out of the plate 18. By providing thesebosses 25 on the side of the edges, I am able to obtain a better fit ofthe Wedge 17 in the groove 16; as all the work of this type is generallydone on a punch press and is somewhat rough, and a good contact betweenthe sides of the slot 16 and the sides of the wedge would be difficultto obtain, a few predetermined points of contact are selected beforehandand those are the bosses 25.

I claim:

A bedpost lock comprising a bracket adapted to be secured to the postand having a portion thereof extending from the post, said extendedportion of the bracket having .a tapered slot, a plate having a wedge toone side thereof for engaging the slot,and an arm extending from theplate and offset to the same side as the wedge, said wedge having bosses011 the sides thereof for better engaging the sides of the slot, andsaid wedge and arm having means for securing thereto an angle iron of abed frame.
